Sta-Kon RP7 NYLINS WIRE JOINT 3No14 - 4No12 WHI

The RP7 is sized for three No. 14 conductors up to four No. 12 conductors. It's a one-directional joint, so all the wires enter from the same side and terminate in the connector rather than passing through. If your bundle is larger than four No. 12s, step up to a higher capacity joint instead of forcing the fill.

No. The RP7 is a one-direction joint, meaning every conductor enters the same end and dead-ends inside the connector. It's for terminating a group of wires, not for a through-splice with conductors leaving each side. For a straight inline splice you want a butt splice or a through-type connector.

The body is insulated nylon, and the RP7 is white. On Sta-Kon joints the color is the size code, so white identifies the 3 No. 14 to 4 No. 12 range. If you're standardizing a panel or a fixture whip crew, pulling by color keeps the right capacity in the right hands.

They do the same job in a junction box, but differently. A wire joint like the RP7 is a crimp style terminating point for a group of conductors running one direction, so it needs the matching crimp tool and gives you a fixed, non-reusable termination. A twist-on connector is hand-installed and can be taken apart. Where a spec calls out crimped, UL listed joints for vibration or for a permanent splice, the RP7 is the right family.

Order Sta-Kon RP7. That single part number covers the white nylon insulated joint rated for three No. 14 through four No. 12 conductors, so there's no separate color or size suffix to specify.

Country of origin on the RP7 is the United States, which matters if you're buying against a domestic-preference or Buy American requirement on a government or institutional job.
